Hi Al,
I don't care to put the registration numbers on the tender itself, I prefer to leave it clean... Pretty much the only time I put the numbers on, anyway, is in a place like Florida, where the Water Nazis are extra vigilant...
My tender has a number of 'customized features' that I've documented with photos... If it was ever stolen, but I managed to relocate it again, I think I'd have a decent argument that it was mine... (grin)
best regards,
Jon
